Vendors sell different vial sizes — comparing sticker prices is misleading. A $30 vial of 5mg works out to $6.00/mg, while a $55 vial of 10mg is only $5.50/mg. The $55 option is actually cheaper per unit of research material.
📐 Formula: Discounted price ÷ mg = cost per mg
Example: $45 after discount ÷ 10mg = $4.50/mg. The table above calculates this automatically for every vendor, so you can compare apples to apples instantly.
When evaluating vendors for TB-500, also check for: Certificate of Analysis (COA) availability, third-party HPLC or mass spectrometry verification, US-based shipping if timing is important, and responsive customer support.

TB-500 is a synthetic peptide fragment of Thymosin Beta-4 (Tβ4), a naturally occurring protein that regulates actin — the fundamental structural protein in virtually every cell in the body. The specific fragment used in research is the actin-binding domain of Tβ4: the sequence Lys-Pro-Ala-Leu-Tyr-Ser-Ile-Lys-Ser-Ala-Lys-Lys (positions 17-23 of the full Tβ4 sequence). Thymosin Beta-4 itself is a 43-amino acid peptide found throughout the body in high concentrations, particularly in platelets, macrophages, and T-cells. It plays essential roles in cell migration, angiogenesis (new blood vessel formation), wound healing, and anti-inflammatory signaling. TB-500, as the active fragment, is studied for its potential applications in musculoskeletal research, cardiac tissue repair models, and neurological recovery protocols.
TB-500 pricing is influenced by: **Fragment vs full Tβ4**: Some vendors sell the full Thymosin Beta-4 protein while most sell the shorter TB-500 fragment. The fragment is cheaper to synthesize but many researchers prefer it for its targeted activity. **Market competition**: TB-500 is a high-demand peptide with multiple vendors offering it, which keeps prices competitive. The $/mg spread across vendors is narrower than less common peptides. **Purity specifics**: The TB-500 sequence is relatively short and straightforward to verify by mass spectrometry. Quality vendors will show exact MW confirmation at 1322.6 Da.
TB-500 quality checklist: **Molecular weight verification**: TB-500 has an exact MW of 1322.6 Da. Insist on mass spec confirmation — this is the clearest way to verify you have the correct compound and not a truncated sequence. **Purity by HPLC**: ≥98% is achievable for this peptide and should be the minimum standard. A COA showing 95% or lower is a red flag for a peptide this size. **Combination products**: The BPC-157 + TB-500 blend is popular and often economical — check if a blend offers better $/mg for the combination than buying separately.
**TB-500 vs BPC-157** Different mechanisms that many researchers consider complementary. TB-500 primarily affects actin dynamics and cellular migration; BPC-157 primarily affects nitric oxide and vascular growth factor pathways. The combination is widely used in musculoskeletal repair research. At current pricing, both are available from around $2.46/mg at the cheapest vendors. **TB-500 vs Full Thymosin Beta-4** TB-500 is a fragment (the active portion) of the full Thymosin Beta-4 protein. Full Tβ4 is significantly more expensive and less commonly available. For most research applications studying actin regulation and tissue repair, TB-500 is the more practical and economical choice.
Based on our current data across 12 vendors, Ion Peptides currently offers the best cost-per-mg — $2.46/mg when you use code Glowlab. Always compare $/mg rather than sticker price since vial sizes vary significantly.
Price variation reflects batch size, synthesis purity, third-party testing costs, and shipping infrastructure. Cheaper doesn't always mean lower quality — some vendors simply operate more efficiently. That said, always verify a Certificate of Analysis (COA) before purchasing from any vendor.
Divide the discounted price by the milligrams per vial. Example: $50 for 10mg = $5.00/mg, while $35 for 5mg = $7.00/mg. The $50 option is cheaper per unit even though the upfront cost is higher. Our table above handles this calculation automatically.
